"Vaccinated people can be asymptomatic carriers."
To put this statement in context, it is also true that a at a target range, a blind person spun randomly around "can" hit a target the size of a dinner plate at 100 yards.
I posted this previously, but:

So let's put some numbers to this. The study term was 13 weeks, and the participants were front line workers. Of the 2,479 people in the study who were fully vaccinated, just three contracted the COVID, which is in line with the vaccine's efficacy. In comparison, the CDC also tracked 994 people who were not vaccinated, and 161 contracted COVID-19. No one in the study died.
So first, a vaccinated person could be a carrier... they do become infected, at a rate 1/134th that of the unvaccinated. The evidence we have strongly suggests the asymptomatic cases -- people with a full on infection but without symptoms -- do not spread COVID. The recent CDC directive lowered the threat level of fomites (exhaled droplets on surfaces and such) to the equivalent of non-existent.
No serious person being honest has a legitimate way to support the theory that fully vaccinated people should go around in face diapers. The only possible purpose of this guidance is population control.... specifically, without the fear level remaining high, extreme government actions are less popular. It's really that simple. And frankly, it goes against the public good. Without the lure of "you can take your mask off" a significantly lower number of people will get vaccinated. This policy makes the vaccine seem less effective than it truly is... and less desirable.
